Barcelona is the latest European city to look towards cutting road traffic in a bid to tackle air pollution, carbon emissions road safety, and promote social cohesion in a more sustainable city centre environment. The goal of cutting inner city road traffic by 21%, and in the process freeing up nearly 60% of the city’s streets, is laid out in the council’s plan including 300km of inner city bicycle lanes.Most important are the introduction of superblocks, which look to limit traffic to arterial routes, around an area of nine-or-so existing blocks. This will open up smaller streets to bicycles, pedestrians and business vehicles, cultivating growth of green, safe and community spaces. The project’s budget is an initial €10m, and the first steps will be low level things, such as changing road signs.
